I just read some text messages between my SIL and my BW. In those, my SIL had stated she doesn't really think of me as her brother anymore, and when my BW asks what she feels about me, she just says she tried not to think of me.
This isn't anything I didn't already know...it just confirmed what I already had thought.
I feel very defeated about my relationship with her. She lives far. So I don't see her much, and don't really have opportunities to really improve things. It is just 4 months out since the whole truth came out, so maybe someday...but I doubt it.
